Construction & Design

The intake tube is crafted from high-density polyethylene (HDPE) using a rotational molding process, which creates a smooth, seamless surface that promotes laminar airflow and minimizes turbulence. This design increases the volume of air reaching the engine, contributing to enhanced combustion efficiency. The HDPE material also offers excellent heat resistance, helping to reduce heat soak and maintain cooler intake air temperatures for better performance.

The included K&N air filter features multiple layers of oiled cotton gauze, providing exceptional filtration while allowing high airflow rates. The filter is designed to be washable and reusable, offering long-term value and consistent performance throughout its service life.
